Background Limited critical care subspecialty training and experience is available in many low- and middle-income countries, creating barriers to the delivery of evidence-based critical care. We hypothesized that a structured tele-education critical care program using case-based learning and ICU management principles is an efficient method for knowledge translation and quality improvement in this setting. Methods and interventions Weekly 45-min case-based tele-education rounds were conducted in the recently established medical intensive care unit (MICU) in Banja Luka, Bosnia and Herzegovina. The Checklist for Early Recognition and Treatment of Acute Illness (CERTAIN) was used as a platform for structured evaluation of critically ill cases. Two practicing US intensivists fluent in the local language served as preceptors using a secure two-way video communication platform. Intensive care unit structure, processes, and outcomes were evaluated before and after the introduction of the tele-education intervention. Results Patient demographics and acuity were similar before (2015) and 2 years after (2016 and 2017) the intervention. Sixteen providers (10 physicians, 4 nurses, and 2 physical therapists) evaluated changes in the ICU structure and processes after the intervention. Structural changes prompted by the intervention included standardized admission and rounding practices, incorporation of a pharmacist and physical therapist into the interprofessional ICU team, development of ICU antibiogram and hand hygiene programs, and ready access to point of care ultrasound. Process changes included daily sedation interruption, protocolized mechanical ventilation management and liberation, documentation of daily fluid balance with restrictive fluid and transfusion strategies, daily device assessment, and increased family presence and participation in care decisions. Less effective (dopamine, thiopental, aminophylline) or expensive (low molecular weight heparin, proton pump inhibitor) medications were replaced with more effective (norepinephrine, propofol) or cheaper (unfractionated heparin, H2 blocker) alternatives. The intervention was associated with reduction in ICU (43% vs 27%) and hospital (51% vs 44%) mortality, length of stay (8.3 vs 3.6 days), cost savings ($400,000 over 2 years), and a high level of staff satisfaction and engagement with the tele-education program. Conclusions Weekly, structured case-based tele-education offers an attractive option for knowledge translation and quality improvement in the emerging ICUs in low- and middle-income countries.

Septic shock is a life-threatening condition that frequently progresses to multi-organ dysfunction despite optimal standard-of-care therapies. Extracorporeal blood purification (EBP) techniques have gained attention as adjunctive strategies aimed at modulating hyperinflammation and supporting failing organs. We describe the case of a 64-year-old woman with septic shock, likely secondary to urosepsis, complicated by acute respiratory failure, acute kidney injury, acute liver failure, and cytopenias. Initial management with fluid resuscitation, empirical broad-spectrum antibiotics, corticosteroids, and non-invasive ventilation proved insufficient. Given profound hyperinflammation (IL-6: 47,089 pg./mL) and severe metabolic derangements, continuous veno-venous hemodiafiltration (CVVHDF) with hemoadsorption was initiated, resulting in rapid IL-6 reduction and hemodynamic stabilization. As her clinical course evolved, a multimodal EBP approach, including sequential hemoadsorption devices, therapeutic plasma exchange, and the double plasma molecular adsorption system (DPMAS), was employed to support renal and hepatic function, at one point requiring two separate extracorporeal circuits operating concurrently for different EBP modalities. Progressive respiratory failure necessitated invasive mechanical ventilation, prone positioning, and subsequent tracheostomy. The patient ultimately recovered, with restoration of hepatic and renal function, resolution of cytopenias, and successful weaning from mechanical ventilation. This case underscores the potential role of adjunctive multimodal EBP in refractory septic shock with severe multi-organ failure. Although clinical improvement paralleled biomarker reduction, causal inference is limited by the concurrent use of multiple therapies. Robust randomized studies are needed to clarify optimal protocols, timing, and patient selection for combined extracorporeal strategies in critical sepsis.

Introduction Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is not primarily a neurotropic virus. However, since angiotensin-converting enzyme 2 (ACE2) receptors are present in the brain, spinal cord, and nerves, the involvement of the nervous system, which could potentially influence the final outcome, cannot be ruled out. This study aimed to assess the incidence and significance of specific neurological manifestations and/or neurological disorders in critically ill COVID-19 patients treated in low-resource settings (LRS), as well as to determine their impact on the clinical outcomes of these patients. Subjects and methods The research was designed as a retrospective observational study conducted between October 2020 and February 2021, during the second wave of the COVID-19 pandemic. The incidence of specific neurological manifestations and/or neurological disorders in patients treated at the Medical Intensive Care Unit (MICU) of the University Clinical Centre (UCC) of the Republic of Srpska, Bosnia and Herzegovina, was monitored, and relevant demographic and clinical data were collected. The results were analyzed using methods from descriptive statistics and statistical testing. Results Among the 262 patients who met the inclusion criteria, 154 (58.5%) exhibited at least one of the monitored neurological manifestations or neurological disorders. The most frequently observed were impaired consciousness (19.5%), headache (10.2%), myalgia (8%), loss of taste and smell (7.6%), lower back pain (3.4%), and ischemic cerebrovascular stroke (3.4%). All other recorded had an incidence of less than 2%. In terms of clinical outcomes, 128 patients (48.9%) died, 81 (30.9%) were transferred to a step-down unit, and 53 (20.2%) were discharged home. Using Fisher's exact test, impaired consciousness was found to be significantly associated with a fatal outcome (p = 0.01; OR = 0.33; 95% CI = 0.17-0.64), while acute polyradiculoneuritis was associated with a favorable clinical outcome in the form of discharge home (p = 0.04; OR = 0.96; 95% CI = 0.91-1.01). Headache was more frequently reported in female patients (p = 0.03; OR = 2.51; 95% CI = 1.10-5.80). Impaired consciousness was significantly more frequent in patients aged 51-60 years (p = 0.02; OR = 2.61; 95% CI = 1.12-6.12) and those aged ≥71 years (p = 0.01; OR = 0.36; 95% CI = 0.18-0.73), while epileptic seizures were most commonly observed in the 31-40 age group (p = 0.01; OR = 0.36; 95% CI = 0.18-0.73). Conclusion The incidence and significant associations between specific neurological presentations and/or disorders and clinical outcomes, along with observed demographic variations, highlight the importance of comprehensive monitoring of extrapulmonary manifestations (including neurological) in critically ill COVID-19 patients.

 In low-resource countries, where sleep medicine centers are limited, screening tools are essential for identifying individuals at risk for obstructive sleep apnea (OSA). This study aimed to identify additional factors that, in combination with the Berlin Questionnaire (BQ) and the Epworth Sleepiness Scale (ESS), could improve the identification of hypertensive patients requiring further evaluation. This cross-sectional study was conducted at the Family Medicine Service of the Public Health Institution \"Dr. Mladen Stojanovic\" in Laktasi, Bosnia and Herzegovina, which serves approximately 35,000 inhabitants. Using a questionnaire with defined important parameters alongside screening tools - BQ and ESS - the study aimed to present descriptive indicators of the observed population and to determine identifiers of sleep disorders (primarily OSA) using the chi-square test. A total of 500 patients with arterial hypertension (254 females and 246 males; median age 60 years (IQR: 50-68 years) and median body mass index (BMI) 26.9 kg/m² (IQR: 24.8-29.8 kg/m²)) were screened using the BQ and the ESS. High risk for sleep disorders was identified in 25.4% of subjects using the BQ and in 25% using the ESS. Smoking, alcohol consumption, a history of causing a traffic accident, and the use of sleeping pills were correlated with positive results on both screening tests.  Patients with arterial hypertension who smoke, consume alcohol regularly, have a positive history of causing a traffic accident, and use sleep medications may benefit from screening for OSA and consideration for referral to sleep medicine centers.

Purpose: To determine whether severe hypoalbuminemia (<25 mg/L) has a significant effect on serum levels of vancomycin and whether it can effect vancomycin dosage regimen and the loading dose administration. Material and Methods: Prospective, cohort, and a single-center study included 61 patients whose vancomycin serum levels were measured in steady state. Vancomycin trough levels (C min) that were in the range 15 to 20 µg/mL were considered therapeutic and trough levels higher than 15 µg/mL were considered potentially nephrotoxic. Results: In the group of patients with severe hypoalbuminemia, C min was significantly higher compared to the those with nonsevere hypoalbuminemia (>25 mg/L; 23.04 [19.14] vs 13.28 [11.28], P = .01). In the group of patients who received the vancomycin loading dose of 2 g, C min was significantly higher in patients with severe hypoalbuminemia compared to the patients with nonsevere hypoalbuminemia (34.52 [25.93] vs 15.37 [10.48], P = .04). Conclusion: In critically ill septic patients with severe hypoalbuminemia, there is a high probability that the loading dose of vancomycin is not necessary since it is associated with potentially toxic vancomycin C min, while in the patients with nonsevere hypoalbuminemia the loading dose may be necessary to achieving therapeutic C min.

Acute respiratory distress syndrome (ARDS) is a severe clinical condition characterized by acute respiratory failure and a high mortality risk despite conventional mechanical ventilatory support. Veno-venous extracorporeal membrane oxygenation (vvECMO) has emerged as an effective life-support technology for patients with ARDS. However, complications may arise following the decannulation of vvECMO, with a relatively frequent development of systemic hyperinflammation (SHI). Among the various treatment strategies for SHI, the use of hemoadsorption with CytoSorb® has shown promising results in removing excessive levels of cytokines and attenuating the hyperinflammatory response. In this case series, we present three critically ill patients with ARDS secondary to pneumonia who underwent vvECMO and subsequently received prophylactic hemoadsorption with CytoSorb® following decannulation as a part of our clinical practice. This case series aims to describe the potential positive effects of hemoadsorption in preventing the development of SHI after vvECMO decannulation in ARDS patients.

Drowning remains a significant global health concern, claiming over 300,000 lives annually, with a disproportionate impact on young individuals in low-and middle-income countries. Conventional mechanical ventilation, while common, falls short in addressing the hypoxemia and hypercapnia often observed in severe near-drowning cases. Veno-venous extracorporeal membrane oxygenation (vvECMO) emerges as a critical intervention for cardiopulmonary failure post-drowning. This case report delves into the pivotal role of ischemia–reperfusion injury (IRI) in a near-drowning-related pathology. Following the initial insult, reoxygenation exacerbates the inflammatory cascade, resulting in a surge of pro-inflammatory mediators. In this context, CytoSorb ® , a hemoadsorption cartridge, demonstrates promise by effectively removing these mediators from circulation. This report outlines its application in a critically ill adolescent patient who experienced near-drowning, presenting a compelling case for CytoSorb as an adjunctive therapy in managing IRI-induced hyperinflammation.

End-stage renal disease and its treatment with continuous ambulatory peritoneal dialysis (CAPD) can affect almost all organs and organ systems including vascular endothelium. Consequently, disturbance in the production of vasoactive substances endothelin-1 (ET-1) and nitric oxide (NO) occurs in these patients. There are only a small number of studies that investigated the impact of long-term CAPD on imbalance in production of vasoactive substances ET-1 and NO among these patients. Therefore, our study aimed to investigate the impact of duration of CAPD on potential overproduction of ET-1 and NO in uremic patients. This study included 23 uremic patients [10 males, mean age: 56.3 (±16.2) years] treated with CAPD. All studied patients were further divided into subgroups, groups A and B. Group A included patients on treatment with CAPD <5 years, and group B included those on treatment longer than five years. Our results showed that serum levels of these vasoactive substances are significantly higher among patients treated with CAPD longer than five years (ET-1: 51.24 ± 32.11 vs. 139.53 ± 42.42; NO: 15.50 ± 2.57 vs. 26.57 ± 5.96, respectively). We concluded that imbalance in production of vasoactive substances is present in long-term CAPD treatment and this imbalance can lead to disturbance in the local blood flow control.

Background and Objectives: Coronavirus disease 2019 (COVID-19) is a novel infectious disease that has spread worldwide. As of 5 March 2020, the COVID-19 pandemic has resulted in approximately 111,767 cases and 6338 deaths in the Republic of Srpska and 375,554 cases and 15,718 deaths in Bosnia and Herzegovina. Our objective in the present study was to determine the characteristics and outcomes of critically ill pregnant/postpartum women with COVID-19 in the Republic of Srpska. Materials and Methods: The retrospective observational study of prospectively collected data included all critically ill pregnant/postpartum women with COVID-19 in a university-affiliated hospital between 1 April 2020 and 1 April 2022. Infection was confirmed by real-time reverse transcriptase polymerase chain reaction (RT-PCR) from nasopharyngeal swab specimens and respiratory secretions. Patients’ demographics, clinical and laboratory data, pharmacotherapy, and neonatal outcomes were analysed. Results: Out of the 153 registered pregnant women with COVID-19 treated at the gynaecology department of the University Clinical Centre of the Republic of Srpska, 19 (12.41%) critically ill pregnant/postpartum women (median age of 36 (IQR, 29–38) years) were admitted to the medical intensive care unit (MICU). The mortality rate was 21.05% (four patients) during the study period. Of all patients (19), 14 gave birth (73.68%), and 4 (21.05%) were treated with veno-venous extracorporeal membrane oxygenation (vvECMO). Conclusions: Fourteen infants were born prematurely and none of them died during hospitalisation. A high mortality rate was detected among the critically ill pregnant/postpartum patients treated with mechanical ventilation and vvECMO in the MICU. The preterm birth rate was high in patients who required a higher level of life support (vvECMO and ventilatory support).

Introduction: Hydrogen ion concentration which is expressed as pH value is in human blood maintained in narrow physiological range (7.36-7.44 in arterial blood). This range is crucial for normal functioning of most biochemical reactions. Extreme acidosis with pH < 6.8 is incompatible with life, unless pathophysiologic process is rapidly reversed. Timely, standardized, and structured approach to assessment and management of extreme critical illness is essential to maximize the chances of patient’s survival. Cases: We present a series of 3 critically ill patients admitted to Medical intensive care unit (MICU) diagnosed with extreme metabolic acidosis (pH ⩽ 6.8). Each patient was treated using Checklist for Early Recognition and Treatment of Acute Illness and INjury (CERTAIN) which is a standard decision support tool in our MICU. Causes of extreme metabolic acidosis included hemorrhagic shock, sepsis, and acute renal failure and diabetic ketoacidosis. Rapid assessment, prompt resuscitation (IV fluids, vasopressors, mechanical ventilation, and renal replacement), and application of specific causal treatment led to positive outcomes in all 3 patients. Discussion: Medical physiology textbooks set the lower limit of pH value at which life is possible to 6.8. However, examples from clinical practice show that if adequate resuscitation measures are taken early in the acute phase of the disease, the biochemical cascade of reactions that are considered irreversible (at pH ⩽ 6.8) may be reversed after all. Conclusion: Critical care approach to extreme metabolic acidosis is a prime example of applied clinical physiology where basic science and clinical practice connect. With these case series we show that timely and structured approach to critical illness shifts the boundaries of reversibility for some of the most severe physiologic derangements.
